Installed rear wheel after tire change. Questions still

[Kozman01]

Hello all. Stripped down the rear according to manual to remove rear tire. I did it that way simply to get some practice tearing the bike apart. Lol. Anyways, sent the tire off to my shop and why the tire was off, had the wheel powder coated to match the powder coated black gloss front. I get tire/ wheel back and start to put it back on and I think I have successfully done so. Well to a point. I think I've tried "Aligning" the rear axle over 10 times, probably overthinking it. Matching punch marks, measuring with calipers, counting threads. Every method says the other one is off. Don't even get me started on belt tension!! Anyways, I had a few questions.

1. Is the rear caliper bracket have a little movement in it? I know there wasn't any bolts to reinstall it as it simply slides on the rear swingarm, but I see the caliper move ever so slightly when the wheel is in motion.

2. Does the rear pully have any movement in it after the axle is tightened according to spec? The pully went on no problem and I held it on with zip ties when reinstalling. I can grab the pully at a 12 and 6 position and it'll move ever so slightly. I would have thought the spacer on the axle would hold that in tight?

3. Before I removed the tire, my belt ran on the left side of the pully as you look at the rear wheel. Now it runs on the right side of the pulley. Should I be concerned?

2017 Voyager. Axle torqued to 80-ftlb. In advance, thank you for any guidance. If anyone has any better way to align the rear axle, I'll listen to anything. I might just fall back on the swingarm punch marks. How off can they be? Maybe I'm just way over thinking this and should just line up the marks, make sure the belt is in the 10mm range and let it be? Thanks again!!
